4 channels mixer voltage controlled
The audio mixer schematic proposed is developed around four amplifiers built inside the SSM2024 produced by Precision Monolithics Inc. (PMI) and is voltage-controlled (VR). The maximum VR voltage is 5.5 volts. The signal-to-noise ratio is 90 dB, and the bandwidth...
Audio Mixer
Three audio circuits are combined in the circuit shown. Each input is connected to its own level potentiometer (R1, R2, or R3), and they are combined at the gate of FET Q1. The output of Q1 is coupled to the...
AMU2481 Audio Mixer
The AN12974A Audio Power Amplifier features built-in Automatic Gain Control (AGC) circuitry and Spatializer technology. Spatializer is an exclusive signal processing technology from Desper Products, Inc. that generates surround sound for low-power mobile applications. This technology is based on the...
Voltage Controlled Audio Mixer Circuit
This audio mixer circuit schematic is designed around four current-controlled amplifiers, all integrated within the SSM2024 IC.
The audio mixer circuit utilizes the SSM2024 integrated circuit, which features low-noise, high-performance operational amplifiers suitable for audio applications. The SSM2024 is particularly advantageous...

Audio Mixer with preamplifier
The mixer is the common "virtual earth" mixing amplifier, and there is nothing special about it. Note that it is inverting, which complements the tone controls (also inverting) so the absolute signal polarity is maintained. As shown, the mixer also...
Electronic Diagram Mixer Audio
This circuit, referred to as an Audio Mixer, is a very simple design that utilizes easily obtainable components. Typically, audio mixer circuits require several integrated circuits (ICs); however, this particular audio mixer circuit relies solely on transistors as its foundation....
Unity-Gain Four-Input Audio Mixer Circuit
The circuit has four inputs. The voltage gain between each input and the output is maintained at unity by the relative values of the 470 kΩ input resistor and the 470 kΩ feedback resistor.
The described circuit operates as a voltage...
